Toall @hom t may conc-em:

Be it `known that I, PERCEY E. VOODRUFF,

a citizen ofthe United' States of America, residing ati-Farmington, inthe county of Vhitman and State of Washington, have 1nventednewA andmuseful. Improvements inv Plow Attachments, of which the following is a specification.l f g The object of the invention is to provide a device for use in conjunction with sulky plows whereby the rear furrow wheel may be shifted to various 'angular positions to keep the jplow so disposed as to throw the furrow uphill or downhillwhen plowing on the side of a hill, thel improved attachment including manually operableineans within easy reach of the plowman for shifting the said furrow y wheel tothe various desired angular positions. e e

The inventionfis illustrated and described in a specific embodiment, to which, however, it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction; to practice may suggest, in `so far'as such changes or alterationsv are compatible in spirit withthe annexed'claims.V l j f Vln the accompanying drawings: v

Figure 1 is aview in side4 elevation of a sulky plow on which the improved attachment is employed. V i

Fig. 2 is a detailed perspective view of the furrow wheel shifting device.

Fig. 3 is a detailed view partly in plan andpartly in section of the operating lever, and its attendant rack.

Fig. L1 is a top plan view of that part of the'mechanism connected with'the rear wheel structure.

Referring to the drawings, the invention is shown applied to a gang sulky plow having the ground working elements 1, the beam 2 from which the ground working elements are swung, the landside wheel 3, the forward furrow wheel Ll and the rear furrow wheel 5. All of these parts are Vof the ordinary well known construction and the plow is designed to be drawn by means attached to the forward end of the beam structure 2 -that is, attached at the end indicated at 6.

A tongue 7 is provided by means of which the plow may be turnedwhen its direction of movement is desired, and this tongue piv otally connects with the standard 8 ofthe specification of Letters Patent. Patentgd Oct, 7, 1919, Application led April 3, 1919. -Serial No. 287,223.

upper end thereof, the standard being part of the plow structure. The tongue 7 is mounted to swing in a vertical planeY by the pivotal connection indicated` at 9, the tongue at this 1point being connected to the arm 10, which hasformedtherewith laterally and forwardly projecting arm 11. .The arm 11v at itsextremity pivotally connects with a longitudinally extending rod forbar'12 ad' jacent the. rear end of which there is carried a' Ulshaped member Vformed with a relatively longrweb portion 13,-,and two relatively short legsv14, these legs being formed with eyes by means of which av sliding en-y gagement is effected between the U-shaped; This U,

shaped member is formed with a rearwardly` member and therod or bar 12.

and laterally extending` arm 15,' which piv otally connects, `as indicated at 16, withl an arm 17 formedfat the upper end of a standard 18 at the lower end of which the rear furrow wheel 5 is rotatably mounted. The standard 18 isfmounted for rocking movement at the rear4 en d of the plow beam 2, s o

that the` axis of rotation ofthe furrow wheel 5 may be changed with reference to the axis of the other wheel.

.Loosely mounted upon the bar 12 between legs 14 of the U-shaped member there is a collar 19, to which there is pivotally connected one end of a connecting rod 20. Compression springs 21 are lnterposed between the legs 14 and the collar so that they stand on opposite sides of the collar, and tend normally to hold the collar evenly spaced between the two legs.

The remaining end of `the connecting rod 20 pivotally connects with a hand lever 22, this lever in turn being pivotally connected at the lower end of a toothed sector 23, and having a. spring held manually operable latch 24, which engages between any two teeth of the sector to hold the lever in various angular positions with reference to the sector. The sector is designed to be Vheld stationary with reference to the bar 12,

to the bar 12 'either in one direction or the other depending on how the tongue 7 is turned.. This-willobviously carry the seetor 2B andA its attendant parts and the U-shaped member and its attendant parts either forwardly, or rearwardly with the result that the standard 18 of the rear furrow wheel is rocked in its bearings to change the aXis of rotation of the rear furrow wheel forthe obvious purpose of .guiding the machine. In order to Vkeep the ground working elements l ofthe lmachine v ink a furrow when plowing on the side of a hill throwing :thei'furrow up the hill'-, it is necessaryitoshift therearfurrow wheel 5 solf-that its axis -of/ rotation will tendl tomovevthe rearend of the machine upthev hill; This iseifecte'dby releasing the latchf 24 y.andlshifting :the lever '22Y backwardly,

wheni the U-shaped` member ismovedbaclrwgardly alongffthe rod l2 'and the standardlS-turned to 'givethegrear furrow wheel the' desiredV position. The springs 2l interposed bythe collar l9fa`nd*the U'-shaped` member"V cushion the vibrations imparted to the rear furrow f wheel- *and permit slight rockingl of standard 18 without imparting tof-the 'plow structure theintermittent shocks that fwouldf resultl from" such vibrations.- Moving'thelever 22v backwardly will ob#- otherwise vious'lyhold the rear of the plow up thevhill when throwing'f they furrow up the -hill andy it is,` therefore, apparentthat-the movementof the lever 22` forwardly will shift the'fur# f row wheel to such a position aswill tend to Vhold the rearfof Vthefplow up the hill whenfthrowing' the lfurrow down the hill.

From' the foregoingdescription andl they accompanying drawings, it is believed that a clear enough understanding? of 'theinvention' is :to be had ltofrenderffurther descriptionunnge'eessary: f
